Do Waterproof Raincoats Really Keep Kids Dry? Testing What Matters

Yes, a properly made waterproof raincoat keeps kids genuinely dry, while most padded kids winter coat styles will soak through in steady rain unless the shell itself is waterproof. We put a yellow waterproof raincoat and an insulated kids winter coat through a thoroughly soggy stretch of weather to see which one children actually stayed dry in, and what specs matter when you're shopping.

What "waterproof" actually means on a label

• Waterproof rating: measured in millimetres, this is how much water pressure the fabric withstands before it leaks. Anything from around 3,000mm copes with drizzle and light showers, while 5,000mm and up handles proper rain. The higher the number, the longer the fabric holds out in sustained downpours.
• Water-resistant: this is the slippery one. A water-resistant jacket shrugs off mist but wets out in real rain. Lots of fashion coats use this term, so read carefully.
• Seams: taped seams matter as much as the fabric rating. Untaped stitching is literally a row of needle holes, and water wicks straight through them. Check the inside of the coat for taped seam lines.
• DWR coating: the durable water repellent finish that makes rain bead up and roll off. It wears out with washing and age, but you can revive it with a reproofing spray.

If you want a plain-English rundown of what different coat types do, this guide to winter coats for kids breaks down the styles children will actually keep on.

How our two test coats performed

We tested both coats on the school run, at the park and on a very wet Sunday walk, with the same child alternating between them.

The yellow waterproof raincoat was the clear winner in wet weather. The taped seams and proper hood kept everything dry through a full park session in heavy rain, and the bright colour is genuinely useful for keeping an eye on kids near roads in gloomy weather. The insulated coat, meanwhile, is brilliant at its actual job: keeping a child warm on freezing dry mornings. It just isn't a rain garment, and no amount of padding changes that.

When a kids winter coat beats a raincoat

A kids winter coat wins whenever cold is the enemy rather than water. Think frosty morning drop-offs, the walk to school in January, and standing on a touchline. Insulation traps warm air around the body, and a good hood and cuffs stop heat escaping.

The honest answer for most families is that you need both. The raincoat covers September to December and April showers, the winter coat covers the cold snap, and on genuinely filthy winter days you can layer the raincoat over lighter layers. This roundup of boys' outerwear shows how retailers split the categories, and the same logic applies to girls' ranges like girls' winter jackets.

Features that matter most for staying dry

• A real hood, not a token flap. It should have a stiffened peak or good depth so rain doesn't pour straight in. Fixed hoods generally fit better than detachable ones.
• Storm cuffs. Elasticated or adjustable cuffs keep sleeves from soaking up puddle water the moment hands go down.
• Coverage length. A raincoat that ends at the waist loses to a longer cut the moment a child crouches. Changing-robe style coverage is even better for swimmers and beach trips, which is where a childrens changing robe earns its keep, doubling as a warm room to change in after wild swimming or football.
• Zips with storm flaps. Zips are the weakest point on any waterproof. A flap over the zip makes an enormous difference.
• High-visibility colour. A yellow or other bright shell helps drivers spot kids on dark, wet afternoons.

Keeping the waterproof working

Waterproof coats stop working mostly through neglect, not faults. Wash them with technical wash rather than standard detergent, which strips the DWR finish, and tumble warm or iron cool afterwards to reactivate the coating. When water stops beading, reproof. Never use fabric softener. Done properly, a decent raincoat lasts through multiple siblings and seasons.

Insulated winter coats need gentler care: follow the care label, avoid high heat which can clump synthetic filling, and dry thoroughly before storing.

Sizing: room for layers, not for growing into

Buy for the season, not for three years' time. A waterproof raincoat should have room for a jumper underneath; a kids winter coat should fit snug enough to trap warm air without a bulky gap at the neck. Check sleeve length with arms outstretched, because cuffs halfway up the forearm let cold air straight in. Adjustable hoods and cuffs buy you a second season, which is the honest version of buying big.

Our verdict

Waterproof raincoats really do keep kids dry, as long as you check the waterproof rating, taped seams and hood rather than trusting the word "showerproof". Insulated coats like our tested kids winter coat are for cold, not wet. Buy both if your child spends time outdoors year-round, get the waterproof rated for real rain, and check current offers on the ToastieExplorer discount page before you buy, where our code gets 15% off all orders. And if you want to make cold, soggy walk mornings less of a battle, small bribes like an rspb bird plush in the pocket or spotting games with kookoo birds toys at home afterwards work surprisingly well.
